Efficient Stark deceleration of cold polar molecules
Stark deceleration has been utilized for slowing and trapping several species of neutral, groundstate polar molecules generated in a supersonic beam expansion. Due to the finite physical dimension of the electrode array and practical limitations of the applicable electric fields, only molecules within a specific range of velocities and positions can be efficiently slowed and trapped. These cons...
متن کاملRydberg-Stark deceleration of atoms and molecules
Correspondence: [email protected] Department of Physics and Astronomy, University College London, Gower Street, WC1E 6BT London, UK Abstract The large electric dipole moments associated with highly excited Rydberg states of atoms and molecules make gas-phase samples in these states very well suited to deceleration and trapping using inhomogeneous electric fields. The methods of Rydberg-Stark de...
متن کاملStark deceleration of lithium hydride molecules
We describe the production of cold, slow-moving LiH molecules. The molecules are produced in the ground state using laser ablation and supersonic expansion, and 68% of the population is transferred to the rotationally excited state using narrowband radiation at the rotational frequency of 444 GHz. The molecules are then decelerated from 420 m/s to 53 m/s using a 100 stage Stark decelerator. We ...
متن کاملRydberg-state-enabled deceleration and trapping of cold molecules.
Hydrogen molecules in selected core-nonpenetrating Rydberg-Stark states have been decelerated from a mean initial velocity of 500 m/s to zero velocity in the laboratory frame and loaded into a three-dimensional electrostatic trap. Trapping times, measured by pulsed electric field ionization of the trapped molecules, are found to be limited by collisional processes. As Rydberg states can be deex...
متن کاملStark deceleration of CaF molecules in strong- and weak-field seeking states.
We report the Stark deceleration of CaF molecules in the strong-field seeking ground state and in a weak-field seeking component of a rotationally-excited state. We use two types of decelerator, a conventional Stark decelerator for the weak-field seekers and an alternating gradient decelerator for the strong-field seekers, and we compare their relative merits. We also consider the application o...
